> ...[the heliosphere] blocks 75 percent of cosmic radiation... It sounds like a solar system-scale Van Allen belt [1] when described like this. So we have at least three layers of cosmic radiation protection identified (heliosphere, outer VAB, inner VAB). If the heliosphere has implications for high-precision, high-accuracy independent-of-Earth interplanetary spaceflight similar to gravimetric and magnetic readings on Earth do for submarines today, then mapping the heliosphere would be a future asset.
